Censorship is the suppression or restriction of access to certain information, ideas, or media by a government or other authority. It is often implemented to control the dissemination of content that is considered offensive, harmful, or politically sensitive. Censorship can take many forms, such as blocking or removing content, imposing restrictions on speech or publication, or monitoring and controlling internet access. This practice raises key ethical and legal questions about freedom of expression and access to information. Researchers in this area may study the impact of censorship on society, analyze the motivations behind censorship efforts, and explore ways to circumvent or mitigate its effects.
